MPC error reporting

MPC generates an EVENTS_MEMACCERR event when an erroneous transaction is detected. The following errors can be detected.

• The address cannot be decoded or the bus Manager does not have permissions to access the Subordinate. When this happens, the MEMACCERR.ADDRESS will capture the failing address issued by the bus Manager port and MEMACCERR.INFO will capture additional access information for the attempted transaction.
• If a transaction is routed to a Subordinate, but the Subordinate responds with an error.

The MEMACCERR registers will not be updated when EVENTS_MEMACCERR is set.
